SUMMARY:S&A Colloquium: Taïssa Danilovich (Monash University)
DESCRIPTION:The effect of evolved star binaries on circumstellar astrochemistry and dust formation\n\nAbstract: \n\nLow- and intermediate-mass stars disgorge their outer layers during the asymptotic giant branch (AGB) phase\, one of the last stages of their lives. Material containing newly-formed elements and a variety of dust and molecules streams out of them in what we call a stellar wind. Studies resolving the extended circumstellar environments of AGB stars have revealed spirals\, discs and bipolar outflows\, with the shaping of the gas attributed to interactions with a companion. However\, most of these companions are not directly observed\, because their light is so strongly attenuated by the dust created around the AGB star. Astrochemistry is the study of molecules\, dust and the chemical reactions that link them in astrophysical environments. I will discuss new methods that combine theoretical astrochemistry with observations to allow us to deduce the nature of the companion stars in binary systems with AGB stars. From this we can begin to understand how companion stars affect the length of the AGB phase. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Ben Stappers (Jodrell Bank / University of Manchester)
DESCRIPTION:Hunting FRBs and Transients with MeerTRAP \n\nAbstract: \n\nMeerTRAP (more TRAnsients and Pulsars) is a fully commensal program running on the MeerKAT telescope to search for transients including FRBs and radio emitting neutron stars. It utilises the excellent sensitivity and wide bandwidth of the MeerKAT telescope to enable it to see faint/distant sources both inside and outside our Galaxy. I will describe the MeerTRAP experiment including our real time analysis systems and our transient buffer which allows us to localise FRBs. I will present some highlights of the FRBs that we have discovered so far including some which have been localised and have associated (high) host galaxy redshifts. I will also present some results on the two repeating FRBs that we have identified. MeerTRAP works with the MeerLICHT optical telescope to undertake simultaneous observations and I will present the latest results from those studies. MeerTRAP has also discovered more than 100 new Galactic transients and I will summarise their properties and discuss some of the particularly interesting sources\, especially those with longer than typical pulsar spin periods. I will also present the detection of a particularly interesting Galactic transient. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Kelly Gourdji (ATNF)
DESCRIPTION:Revisiting GW170817 at milliarcsecond scale: high-precision constraints on jet geometry and Hubble’s constant\n\nAbstract: \n\nThe historic detection of gravitational waves from the electromagnetically bright binary neutron star merger GW170817 enabled the first standard siren measurement of Hubble’s constant (H0). The accuracy and precision of this measurement depends crucially on how well the merger inclination angle is constrained\, given its strong covariance with luminosity distance. Modeling the light curve of the jet’s afterglow provides constraints on inclination\, but is highly dependent on the similarly uncertain jet opening angle. Past studies have improved on this by invoking high-resolution radio observations\, obtained through very long baseline interferometry\, to constrain the viewing angle. In this talk\, I will present our Bayesian visibility-plane model-fitting framework that provides a more informed and robust measurement of the viewing geometry of GW170817\, by including all relevant data\, robustly handling systematic uncertainties\, rigorously sampling model parameter space and using new hydrodynamical jet models. We extend our framework to fit for H0 directly\, and consider various plausible peculiar velocity corrections to present a new and improved standard siren measurement of H0. Strikingly\, we find our result to be in better agreement with one of the two precise and independent H0 measurements that are famously in tension. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Jessica Dempsey (ASTRON / SKAO)
DESCRIPTION:Learning in low frequency: Charting a path for SKA from LOFAR and ASTRON\n\nAbstract: \n\nLOFAR is one of the highest-impact Observatories on the planet. I will discuss its achievements\, technical and scientifically and how vital the path to LOFAR has been\, and will be\, for SKA-Low success. LOFAR2.0 is currently finishing construction and will be operational at the end of 2026. I will show the benefits of aligning the parallel projects\, both scientifically and technically\, and the crucial role the community can play in accelerating the success of both telescopes\, as well as other ASTRON technology initiatives with strong future synergies with next-generation Australian radio astronomy plans. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia
